on the upper rod 7 and substantially bridging the space between a side member 4 and the hub 21 of the gear 19. It is to be particularly noted that the gears 2st and 25 are of the same ratio so that during the operation of the machine the sleeves 23 and 26 will have the same peripheral speed as it is to be understood that these sleeves 2.35 and 26 are also of substantially the same l@ diameter. it is to be noted, however, that the ratio of the remaining gears and pinions is such that the speed of the pinion 9 is gradually reduced so that the sleeves 23 and 26, during the operation of the machine, are 5 caused to rotate a relatively low speed in comparison with the rotation of the shaft l0.

Retrograde movement of the sleeves 23 and 26 is prevented through the instrumentality of the pawl or dog 27 herein disclosed as of a gravity type and which is pivotally supported by a side member i and has coaction with the teeth of the gear 24. A

In the event the motor vehicle should become stalled, as in mud, sand or the like, a cable C is suitably anchored at a point in advance of the vehicle and said cable also wrapped a predetermined number of times around the drum 28 and then up and around the drum 26, the number of such wrappings or turns being dependent upon the load. After this arrangement of the cable C, and the pinion 9 is moved into mesh with the gear 8 and as the motor operates, the drums 23 and 26 will be caused to rotate in a manner whereby direct pull is imposed upon the frame of the vehicle resulting in the extraction of the vehicle from the mud, sand or the like. t is of particular i1nportance that the cable C passes around the sleeve 26 as by this means requisite tension is maintained upon the cable to assure the ldesired pull, it being understood that as the cable passes from the drum 26 it is taken care of by a hand operation, such hand operation imposing sufficient initial tension upon the cable to assure effective operation of the machine. n view of the foregoing it will be readily understood that the sleeves 23 and 26 may also be termed drums, the upper sleeve 2S serving as a tension or friction drum. rr F rom the foregoing description it is "d thought to be obvious rthat a pulling machine constructed in accordance with my'invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my in vention is susceptible of some change and modification without departing from they principles and spirit thereof and for thisreason I do not wjish to be understood as i5 limiting myself to ythe precise y apt-,erangement-- termediate portion ofV the U-shaped frame to the frame of the vehicle with the side members forwardly disposed, said side mem bers at their outer end portions being pro-V vided with upstanding posts, tie rods con necting the outer end portions of the side members of the U-shaped frame and the upper end portions of the posts, a gear freely mounted on the lower tie rod adjacent to a side member of the U-shaped frame, a shaft rotatably supported by said side member 11- and in driving connection with the gear, said shaft being in driven connection with the drive shaft of the motor vehicle, a drum freely mounted on said lower tie rod to one side of the gear, a second gear freely mounted upon the upper tie rod at a point adjacent to the first named gear and in mesh therewith, said second gear being also in driving coni nection with the drum, a second drum freely mounted on the `upper tie rod to one side of the second gear, the ends of both of the drums remote from the gears being in driven connection, and a cable adapted to be wound A on the firstnamed drum and extended to and wrapped around the second drum, said second drum operating to maintain tension upon the cable during a working operation. 2. The combination with the frame of a motor driven vehicle and a drive shaft operated by the motor of the vehicle; of a pulling machine comprising a substantially Uf shaped frame, means for connecting the intermediate portion of the U-shaped frame to the frame of the vehicle with the side memhers forwardly disposed, said side members at their outer end portions being provided with upstanding posts, tie rods connecting the outer end portions of the side members of the U-shaped frame and the upper end portions of the posts, a gear freely mounted` on the lower tie rod adjacent to a side member of the U-shaped frame, a shaft rotatably supported by said side member and in driving connect-ion with the gear, said shaft being in driven connection with the drive shaft of the motor vehicle, a drum freely mounted on said lower tie rod to one side of the gear, a second gear Afreely mounted upon v the upper tie rod at a point adjacent to the first named gear and in mesh therewith, said second gear being also in driving connec- 'tion with the drum, a second drum freely .mounted on the upper tie rod'to one side of the second gear, the ends of both of the drums remote from the gears being connection, a cable adapted to be wound on the first named drum and'extended to and wrapped around the Second drum, said second drum operating to maintain tension upon the cable during a working operation, and means carried by the U-shaped frame and operable at will to make or break the operative connection between the first named gear and the associated shaft.

3. The combination with the frame of a motor driven vehicle and a drive shaft operated by the motor of the vehicle; of a pulling machine comprising Va substantially U- shaped frame, means for connecting the intermediate Vportion of the U-sh'aped frame to the frame of the vehicle with the eide members forwardly disposed, said side members at their outer end portions being provided with upstanding posts, tie rods connecting the outer end portions'of the side members of the U-Shaped frame and the upper end portions of the post-s, a gear freely mounted on the lower tie rod adjacent to a eide member of the U-shaped frame, a shaft rotatably supported by said side member and in drivadjacent to the first nained gear and in mesh therewith, said second gearbeing also in driving connection with the drum, a'second drum freely mounted on the upper tie rod to one side of the second gear, the ends of both of the drums remote from the gears being in driven connection, a cable adapted to be wound on the first named drum and eX- tended to and wrapped around the second drum, said Second drum operating to maintain tension upon the cable during a. working operation, and a pawl carried by -a side member of the U-shaped frame and engageable with the adjacent drum to hold both of the drums against retrograde movement.

In testimony whereof I hereunto aiiix my Signature.
